An Air Source Heat Pump (ASHP) absorbs heat from the outside air which can then be used to heat radiators, underfloor heating systems, warm air convectors and domestic hot water.
Heat from the air is absorbed at low temperature into a fluid. This fluid then passes through a compressor where its temperature is increased, and transfers its higher temperature heat to the central heating and hot water circuits of the property.
Air source heat pumps could lower your fuel bills, provide you with an income through the government's Renewable Heat Incentive (RHI), lower your home's carbon emissions. They require no fuel and very little maintenance, and ear cheaper and easier to install than ground source heat pumps.
How efficient are air source heat pumps?
ASHP's can efficiently heat air temperatures as low as -15˚C.
Where would you put it?
You'll need a suitable location outside your property where a unit can be fitted to a wall or placed on the ground. It will need plenty of space around it to get a good flow of air.
Does my home need to be well insulated?
Since air source heat pumps work best when producing heat at a lower temperature than traditional boilers, it's essential that your home is insulated and draught-proofed well for the heating system to be effective.
How economical are they?
The system will pay for itself quickly if it's replacing an electricity or coal heating system. Heat pumps may not be the best option for homes using mains gas.
Do they work with underfloor heating?
Air source heat pumps can perform better with underfloor heating systems or warm air heating than with radiator-based systems because of the lower water temperatures required.
Is the system intended for a new development?
Combining the installation with other building work can reduce the cost of installing the system.
